SPRING? latest.

To all whom 'it may concern lBe it .known'that I, JEFFERSON D. SHORT,v a citizen of the United, States, residing at l TeXhonia, 'inl thel countylot' Sherman and State of Texas, .have invented certain new and useful `Improvements in4 Spring-VheelS,

of which the following is a specification.

`This invention relates to spring whe-els and Amore* especially to springl wheels for use on motor vehicles, such 'as automobiles andmotor cycles, and my obj'ect is to produce a wheelwhich will absorb tlie'shock or .jar incident to its passage over rough or uneven roadways and which is equipped 1S with a solid instead ot'a pneumatic tire and 'is therefore' non-puncturable.

A; further object is to produce afwheel o this character of simple', strong, durable .and compact construction and'oi neat and at'- v traetive appearance.

With these objectsin view the invention ."consists in oertain'novel and peculiar features oiv construction and organization as hereinafter describedv and claimed; and in order that it may be funy understood refdrawing, in which- 'Ligure' 1, is a side view of a spring wheel .embodying myinvention. Fig. 2, is an en-1 larged section to, illustrate more clearly the construction of the telescopic spokes.' Fig.v

3, is a section showing the pivotal connection between the hub and the inner .end of spoke. Fig. t, is a similar view showing'- the pivotal,

erence is to be'ihad to the accompanying 43-.5 connection between the rim and the outerv end of spoke, y

In the said drawing, 1 indicates the 'hub provided with suitably-spaced,parallel ribs 'Qlaiid 3, pro-vided with alined' holes 4e, the @ribs '3 by preference projecting' outward a igiieater distance than ribsfQ, the spaces betyveen the ribs constituting grooves 5.

hub. The outer members 12Vare widened attlieir outer ends and .are provided with perforated lugs 15 to .engage the ribs') and be' pivotal.l f secured theretoat equi-distant points by pivot pins 16, correspondingin allv `respects to. pivot pins ill, and in this connection it will be-noticed that the pivot pins 1l and 16. taper so lthat they maybe drawn-- fartherthrough the engaged parts as :the pivot holes in the latter become enlarged by wear., and thusy guard agaii'ista rattling noise being produced at the pivotal points when the wheelVv is inl motion. 1 The said .pins are threaded 'atthe'ir smaller ends and 70 are engaged by nuts 171a1id nut locks 18, the `latter being preferably of they split -springtype andmounted upon thepi-ns and interposed between the nuts and the adjacent part of the hub in Fig. 3' and the spoke in 75 Fig. 4.

It will be understood ofcourse that I do not restrictmyselt to the use of the nut lock as other reliable securing means for the pivot pins maybe employed. l g

19 indica-tes springs coniined'in the inner Ortubi'ilar inen'ibers 111 of` the spokes and pressing inwardly upon said members and outwardly on members 12, the springs 19 tending to. hold the hub contentrieally within the rim and in order to exclude dust and water `from the interior 'of members 11 o t' the spokes, smiling boxes #20 are secured ou the outer ends of said members and lit slidin'gly on the members 1t?. as shown most 90 clearly in' Fig.- 2.

Assun'iing that weight is imposed through the axle upon the hub of the wheel, it will be -apparent that the springs ot the underlying spokes will yield and thus permit the hub ,95 of the wheel o occupy a position vertically below the axis ot' the rinnlas indicated by dotted lines in Fig. 1. it being Aalso noted that 'when the hub is thus depressed allot the spokes lying atA opposite sides`of the 100 vertical center of the wheel operate pivotally and that all of the spokes are elongatedv or contracted through 'the telescopicjacti'on of their members occasioi'iedfbj7 the change of position ot the hub, the springs above the 4 horizontal center'of the wheel tending to exert a relativelvsmall pressure downward `-uponthe hub and' the springs below the hub eigertinglan increasing resistance to depresrides; over an Yobstruf'ztion the' telescopic :S'A'plresg-permit the hub tor'move downward -sinneofthe latter. .it .the wheelstrike's and 110V Will cushion such 'movement and absorb the.

'v p'ossessmg the fea'turesof advantage. enustricted to the exact4 mer'ated as desirable" and .I VJish it to be understood4 that I do not desire to be re. details of construction `shown and' describedv as obvious modificatiorus will suggest themselves to one skilled lin the art.

Having. thus described the invention what -I claim as new and desire to. secure by Let-l ters Patent, .1 s:-
